Sequential separation of anti-diabetic drugs in the presence of melamine as impurity using chromatographic methods.

The study of green analytical chemistry has garnered significant attention in the context of mitigating global environmental contamination. In this study, we present two methodologies for environmentally friendly chromatography that enable simultaneous and specific determination of Saxagliptin (SAX), metformin (MET), and a pharmacopoeial impurity of MET known as melamine (MEL). The initial method employed in this study is High-Performance Thin Layer Chromatography (HPTLC), which utilized 60 F 254 silica gel-coated Mark HPTLC plates on aluminum sheets as the stationary phase.

Dietary supplements for prevention of Alzheimer's disease: and molecular docking studies.

Objectives: Alzheimer's disease (AD) is one of the most common neurodegenerative diseases in people over 65. The present research aimed to investigate the potential of different dietary supplements (DS) in preventing AD in an experimental animal model and study.

Materials And Methods: Three DS containing a mixture of wheat-germ oil and black pepper extract/or turmeric extract were prepared.

NOD2 expression in psoriasis before and after treatment with Narrowband Ultraviolet B phototherapy.

Psoriasis is a chronic inflammatory skin condition characterized by hyperproliferation of keratinocytes and immune dysregulation. Narrow band ultraviolet B (NB-UVB) phototherapy is a common treatment for psoriasis due to its efficacy and safety profile. NOD2 is an intracellular pattern recognition receptor involved in immune responses and inflammation, and its expression is elevated in psoriatic skin.

Vitiligo detection capabilities of 1D photonic crystal biosensing design.

This theoretical work focuses on the application of Tamm resonance-based biosensing using a one-dimensional photonic crystal for detecting skin vitiligo, a condition caused by the loss of pigment in the body. This biosensor utilizes the interaction of light with the photonic structure to identify the specific biomarkers associated with vitiligo. The proposed structure is composed of prism/Ag/skin-sample/(GaP/PS)/glass.

The Effects of Electronic Cigarettes on Oral Microbiome and Metabolome in 3D Tissue-Engineered Models.

Background And Aim: Recent studies have shown that electronic cigarettes (ECs) use disrupts the oral microbiome composition and diversity, impairing the metabolic pathways of the mucosal cells. However, to date, no reports have evaluated the role of EC exposure in the context of oral metabolome. Hence, the aim of this study was to investigate the role of EC aerosol exposure in the dysregulation of the oral microbiome and metabolome profile using in vitro 3D organotypic models of human oral mucosa.
